CURL access sytax:
		[http GET]
		curl https://idmapping.uniprot.org/cgi-bin/idmapping_http_client3 -d "ids=ID1,ID2,...,IDn&from=IDTYPE&to=IDTYPE[&async=YES|NO][&taxid=TAXID]" -d "@/[path]/[filename]"
		[http POST]
		curl --request POST https://idmapping.uniprot.org/cgi-bin/idmapping_http_client3 --form "ids=ID1,ID2,...,IDn" --form "from=IDTYPE" --form "to=IDTYPE" [--form "async=YES|NO"] [--form "taxid=TAXID"]
		[ids FILE]
		curl https://idmapping.uniprot.org/cgi-bin/idmapping_http_client3 -d "@/[path/]id_filename" -d "from=IDTYPE&to=IDTYPE[&async=YES|NO][&taxid=TAXID]"
	where 'n' can be any number,
	default async=yes, case insentive,
	the file format of 'id_filename' is: ids=ID1,ID2,ID2,...,IDn, and
	spaces may also be used as delimiters for ids unless the ids are GeneNames.
	CURL examples:
		curl https://idmapping.uniprot.org/cgi-bin/idmapping_http_client3 -d "ids=Q65PH2,Q81VZ2,Q15796&async=NO&from=ACC&to=P_REFSEQ_AC"
		curl --request POST https://idmapping.uniprot.org/cgi-bin/idmapping_http_client3 --form "ids=Q65PH2,Q81VZ2,Q15796" --form "from=ACC" --form "to=P_REFSEQ_AC"
		curl https://idmapping.uniprot.org/cgi-bin/idmapping_http_client3 -d "from=ACC&to=P_REFSEQ_AC&async=NO" -d "@myIdFile"
		(In this case, 'myIdFile' contains: ids=Q65PH2,Q81VZ2,Q15796)
